Has your host done anything to their servers, lately? That error often occurs, after a server upgrade, or similar.

Have a word with them, first, to see if they can help you.

If not, come back and tell us what they say.

Seems like the host has done an OS Update/Upgrade

I have WP and other php emailing systems but it happens only in SMF. So i know what they will say, "The problem is with your script, you need to talk to SMF"
